* lisp/progmodes/m4-mode.el (m4-font-lock-keywords): "dnl"
comments should override any previous syntax-based highlighting
(37132). This makes "dnl foo#bar" be highlighted correctly.
* lisp/emacs-lisp/syntax.el (syntax-ppss): Move the description of
the return value from...
* src/syntax.c (Fparse_partial_sexp): ... here because
`syntax-ppss' is what's called over the place, and jumping through
an indirection to get to the value description is inconvenient.
* lisp/simple.el (read-char-from-minibuffer-history):
Rename from read-char-with-history--history.
(read-char-from-minibuffer-map):
Rename from read-char-with-history--map.
(read-char-from-minibuffer): Rename from read-char-with-history.
(read-char-from-minibuffer-self-insert): New command.
(zap-to-char): Use read-char-from-minibuffer.
* lisp/simple.el (read-char-with-history): Reimplement based on
read-from-minibuffer.
* lisp/simple.el (read-char-with-history--map): New variable
(bug#10477).
* lisp/tab-bar.el (tab-bar--tab): Store additionally point-marker,
frame parameters buffer-list and buried-buffer-list, both for wc and ws.
Use seq-filter.
(tab-bar-select-tab): Restore point-marker after restoring
window-configuration. Also restore frame parameters buffer-list
and buried-buffer-list both for window-configuration and window-state.
(tab-bar-history-limit, tab-bar-history--minibuffer-depth): New variables.
(tab-bar-history-current): Rename from tab-bar-history--pre-change.
(tab-bar-history--pre-change): Set tab-bar-history-current.
(tab-bar--history-change): Use seq-take for tab-bar-history-limit.
(tab-bar-history-back, tab-bar-history-forward): Restore point-marker.
(tab-bar-list-noselect): Use seq-remove.
* lisp/emacs-lisp/seq.el (seq-take, seq-filter): Add autoload cookie.
* doc/lispref/errors.texi (Standard Errors): Mention the new error.
* lisp/files.el (auto-mode-alist): Add a bunch of image suffixes
to the list (bug#37972) based on the output from "gm convert -list
format" (i.e., graphicsmagick).
* lisp/image-mode.el (image-mode): Rewrite to possibly notify the
user about image-use-external-converter.
(image-mode--setup-mode): Factor out into own function and don't
run under `condition-case' as there's nothing here that should
error.
* lisp/image.el (unknown-image-type): New error.
(image-type): Signal that error so that image-mode can offer
sensible feedback to the user.
(completion-metadata): Always return a fresh new cons cell.
(completion--nth-completion): Don't bother calling adjust-metadata
if the result won't be used.
(completion-pcm--hilit-commonality): Revert recent change which had
removed support for `completions-first-difference` in `substring` and
`partial-completion` styles.
(completion--flex-adjust-metadata): Treat the arg as immutable.
* src/xfaces.c (merge_face_vectors) : Pass ATTR_FILTER to
merge_face_ref to stop recursion merging in advance when possible.
(merge_named_face) : add more conditions to potentially reduce calls to
merge_face_vectors in more unneeded situations.
* src/xfaces.c (merge_face_vectors) : Add extra parameter ATTR_FILTER
with the same functionality than in merge_named_face. Update all
occurrences.
(merge_named_face): Remove condition to avoid call
`merge_face_vectors`.
Sometimes, when finding files with icomplete-mode, backward-deleting
the previous word or sexp (to move up a directory) doesn't actually
refresh the file list of the new directory. Forcing redisplay in
icomplete-exhibit misteriously fixes the problem.
* lisp/icomplete.el (icomplete-exhibit): Add call to redisplay.
This tries (not particularly hard) to emulate Ido's magic C-k, C-d,
RET and DEL. For now, the new commands have to be explicitly added to
an active map by the user, using something like this:
(let ((imap icomplete-minibuffer-map))
(define-key imap (kbd "C-k") 'icomplete-magic-ido-kill)
(define-key imap (kbd "C-d") 'icomplete-magic-ido-delete-char)
(define-key imap (kbd "RET") 'icomplete-magic-ido-ret)
(define-key imap (kbd "DEL") 'icomplete-magic-ido-backward-updir))
* lisp/icomplete.el (icomplete-magic-ido-kill)
(icomplete-magic-ido-delete-char, icomplete-magic-ido-ret)
(icomplete-magic-ido-backward-updir): New commands.
* lisp/tab-bar.el (tab-bar-history--pre-change): Store also minibuffer-depth.
(tab-bar-history-change): Check stored minibuffer-depth for zero.
(tab-bar-history-mode): Use prefix -- for internal functions.
* lisp/progmodes/python.el (python-rx): Use `rx-let' instead of
`rx-constituents'. This allows for some slight redundancy reduction,
since `rx-let' definitions are expanded inside `not' (bug#37849).
Reorder some `or' forms for more efficient matching.
* lisp/erc/erc.el (erc-hide-current-message-p): Make
erc-channel-hide-list work (bug#37879) by getting matching on the
channel name instead of the ERC client name.
* lisp/gnus/gnus-cus.el (gnus-group-customize): Decoding is
superfluous here -- everything is utf-8 already.
(gnus-group-customize-done): Don't double-encode the text (bug#37901).
* lisp/net/tramp-sh.el (tramp-maybe-open-connection):
`tramp-encoding-command-interactive' must be the last command-line
switch, at least for bash. (Bug#37953)
Copyright-paperwork-exempt: yes
* lisp/tab-bar.el (tab-bar-back-button, tab-bar-forward-button):
New variables.
(tab-bar-make-keymap-1): Show these buttons in tab-bar-history-mode.
(tab-bar--tab): Add history-back and history-forward.
(tab-bar-select-tab): Restore history-back and history-forward.
(tab-bar-history-omit, tab-bar-history-back)
(tab-bar-history-forward, tab-bar-history-pre-change): New variables.
(tab-bar-history-pre-change, tab-bar-history-change)
(tab-bar-history-back, tab-bar-history-forward)
(tab-bar-history-mode): New functions.
Left over rejected hunks that we forgot to merge by hand should not be
silently ignored. Better explicitly remove/rename .rej files when
done with them.
This is so minibuffer.el can make use of cl-generic
* lisp/minibuffer.el (minibuffer-local-completion-map):
Move switch-to-completions bindings here from...
* lisp/simple.el (minibuffer-local-completion-map): ... here.
* time-stamp.el (time-stamp-time-zone): Support customization with
an integer offset (a new possible value of the ZONE argument to
format-time-string in Emacs 27).
Update the safe-local-variable predicate from string-or-null-p
(describing time-stamp-time-zone's domain before 2015) to new
predicate time-stamp-zone-type-p (describing the current domain).
* time-stamp-tests.el (time-stamp-test-helper-zone-type-p): New test.
* lisp/emacs-lisp/tabulated-list.el (tabulated-list-print):
Don't use count-screen-lines, as it is unreliable when lines
are truncated and the region ends before a newline (the root
cause is in vertical-motion, but is very hard to fix there).
Instead, use vertical-motion directly, as the problems with
counting/not counting the newline that ends the region are not
relevant to what we need in this function, which is simply the
number of the current window line. (Bug#37941)
Often, when using icomplete with icomplete-show-matches-on-no-input
and commands like C-h f, icomplete-exhibit will take a long time (like
several seconds) to show all the completions.
However, if there is a non-nil default value, like when the C-h f is
performed exactly on a function name, the minibuffer prompt will
reflect that immediately. If the user immediately presses RE
(icomplete-force-complete-and-exit) we take that to mean "use the
default" and avoid the long wait.
As an extra performance tweak, this commit also removes an unneeded
call to icomplete-exhibit in icomplete-minibuffer-setup.
* lisp/icomplete.el (icomplete-force-complete-and-exit): Short-circuit
possibility of non-nil minibuffer-default.
(icomplete-minibuffer-setup): No need to explicitly icomplete-exhibit
here since icomplete-post-command-hook will call it unconditionally.
* lisp/net/tramp.el (tramp-call-process): `result' can also be nil.
* test/lisp/net/tramp-tests.el (tramp--test-timeout-handler):
Improve trace format.
The previous algorithm had two problems: it considered non-matches in
the beginning and end of the string as matching "holes" and failed to
penalize larger holes, making flex-score-match-tightness only
effective in some corner cases.
The new formula, which is described in code and in pseudo-code in the
comments, fixes these problems.
As a result, by default, C-h f flex now correctly bubbles up
"company-search-flex-regexp" to the top, in front of "file-exists-p".
With a flex-score-match-tightness smaller than 1.0, the situation is
reversed.
* lisp/minibuffer.el (flex-score-match-tightness): Adjust default
value. Improve docstring example.
(completion-pcm--hilit-commonality): Improve example. Remove unused
variable. Improve algorithm.
